PAUL F. COX; OF CHICAGO, ILLINOIS;

WEB PRINTING PRESS. a:

Application filed May 9; 1921.

To all to from it may concern Be it known that 1, PAUL F. Cox, citizen of the United States, residing. at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful 1mprovements in Web-Printing Presses; and I.

hereby declare that the following is a full, clear, and exact description thereof, refer ence being had to the accompanying drawings, which form part of this specification.

This invention relates to printing presses of the so-called traveling cylinder flatbed web perfecting type in which the cylinders are moved back and forth over stationary type beds and impress the web upon flat forms of type or printing surfaces on said ranged in the same horizontal plane and in close proximity to each other with one of the beds lying between the main crank gears 0r wheels by which the cross heads in which the cylinders are journaled are reciprocated, to move the cylinders back and forth over the beds. This arrangement results in shortening the length of the press several feet, and such shortening of the press also enables various other simplification of construction and lessening of parts as hereinafter pointed out.

Both type. beds are arranged upon the same level at a convenient height from the floor so that they are readily accessible when the pressman desires to place type forms upon or remove them from the beds; and this eliminates the necessity for any pit? customarily provided for other types of traveling cylinder web printing presses. It also enables the pressman to change the color in both ink fountains while the press is in operation which is an advantage and time saving feature which will be readily appreciated by the trade.

By having one of the type beds set between the main crank wheels one of the cyl- Serial No. 467,959.

inderstravels back and forth between themain crank wheels, and thus'the" space ordinarily required merely for the main driving system is utilized for printing, and this construction permits the arrangement of all the infeedmg and outfeeding cyhnders and co acting devices in convenient and compactspace, easily accessible for all. purposes from the drive end of the press.

This invention also enables a large webroll to be placed at the end-of the press atthe end opposite to the driveend, thus leaving a clear floor space for the opera-tor when overcasting or threading the web in the feed and delivery mechanism and around the angle bars to the folder. In the present: invention the folder islocated at the side of the press adjacentthe drive end thereof and the folding mechanism is driven directly from the main crankgears of the machine and in exacttime therewith.

In the form of press shown the cylinders are single acting, orprint only on one strike instead of on both strokes over the beds and the invention includesnovel means for raising andlowering the impression-cylinders-on their alternate strokes; and also novel combinations of parts for all of which protection is desired. In said drawings;

Fig. 1 is a side elevation of the complete press.

Fig. 2 is a longitudinal vertical sectionthereof.

Fig. 3 is a drive end elevation of the press.

Fig. 4 is a detail view of the driving connectionsbetweenthe folder cylinders and the crank gear.

The press shown in the drawings is adapt edto produce and fold newspapers of .41; 6

The, cross heads G and G at each. side of the machine are rigidly connected by a tie bar M so that they move as one. The cross heads are reciprocated longitudinally of the press, (so as to roll the cylindersback and forth over the beds) by means of pitmans E each connected at F to the cross headG and at D to a wrist pin on a main drive gear 0 which is'rigidly keyed to a main drive shaft C suitably ournaled in hearings in the side frames. The drive gears C mesh with'pinions b on a main drive shaft A which may be driven by any suitable means. As shown it carries a pulley A driven by a belt A from a motor A which may conveniently located beneath the bed N.

The cylinder I is journaled in boxes H mounted in eccentrics J which are provided with two arms P and R; the arm P carries the shaft H of the cylinder 1 is journale d in eccentrics l which are provided with arms P and R 'The arm P carries a roller which is adapted to engage a fixed cam Qf attached to the frame of-the press,

just as or before the cross heads G reaches the inward limit of its travel. The arms R and R are connected by a tie rod B so that when one eccentric is rocked the other eccentric is similarly rocked. Thus the cylby alternate engagementof the arms P and P with the cams Q, and Q respectively on the alternate strokes of the cross heads or cylinders.

5 T l The bed 0 is practically arranged above after referred the main drive shaft C and between the main crank gears C so that the cross heads G which move the cylinder 1 move between the gears C this arrangement ma terially shortens the length of the pressyby bringing driving mechanism practically underneath or beside one of the beds.

The cross heads G carry a system of inking rollers hereinafter referred to at the outer side ofeylinder I, and the cross heads G carry a system of inking rollers hereinto at the outer side of cylinder l The cross heads G carry a shaft '5 on Cooperating with these which is mounted arms h carrying a'web guide roller 6 Cross heads'G also carry arms [7&2 in which is supported a web guide roller 6 The rollers 79 and b? are arranged above and at opposite sides of the cylinder 1. A web guide roller 6 is also mounted on the cross heads G at the inner side of the cylinder 1.

The cross heads G are provided with arms M on which is mounted a guide roller 0 at the inner side of the cylinder 1 Cross heads also have arms 72f carrying a guide roller 6 at the outer side of cylinoler I I The roll of web 10 mounted at the end of the press opposite the drive mechanism where it is out of the way. The web roll is preferably mounted on a shaft 22 provided with a pulley 21 which is engaged by a brake shoe 2O pivoted on the frame of the press and having a cam arm 19 engaged by a rolleron a lever 18 pivoted on the press-; frame; and lever 18 is connected by a rod 17 with a crank arm 16 on a rock shaft 15 carrying arms 14 in which is jou'rnaled a roller 0 which rests in a loop its shaft meshing with an intermediate gear which in turn meshes 'with' a driving pinion cl" on the shaft 0 of the crank gear so that the feed roll is driven from the crank gears C by direct and simple means.

From the feed roll ti and around a guide roller 6 mounted in the press. and-then passes horizontally to along and over the first looping roller 6.

The looping roller 6 is mounted in the upper ends of rocking levers f mounted on ashaft 9 journaled in the main frame. The lower end of one or both levers F is pivotally connected by a rod f to the lower end of a lever P which is pivoted at fton the main frame. The lever f carries a roller f which is adapted to engage an equalizing cam f affixed to the shaft of the feed roller 42 so as to turnuniformly therewith, the cam therefore being driven by the same gearing whichdrives the feed roll, doing away with any special gearing for operating this cam. The cam is so constructed as to oscillate the lever F at the proper time to cause the looper e to take up or give out the web as required the operation of the press. The cam f is operated (1 to 7..) with the roll cl. The cams 7* may be inset in the web passes onto of the web W and automatically controls the feed of the ion annie,

main frame to save widtlrof-press andirisure proper alinement. of the levers andparts when operated.

In the construction shown the-cam f isa plane cam and the roller 79 on the lever i is held continuously in contact therewith by a suitable spring. As shownone end of a rod f is pivotally' connected to .the lowerend of the lever f, and the other end ofthis rod is guided in an eye 7 on themain frame; and a helical expansionspring, f is,

interposed between the stop 1 and a collar f on the rod 7. The spring f acts to rock,

then to and up over a stationary roller I) suitably mounted in the frame of the press; then the web passes to and over the roller 12 under the cylinder 1, u over the guideroller 6 on cross heads tar; and then to and over an adjustable register roller 6 adjustably mounted on the frame in any suitable way.

As shown roller Z) is mounted in slidable bars 28 which can be adjusted by hand wheels 29 in the usual manner. From the register roll 5 the web is led back above the cylinder I to and over the guide roller Z1 directions, one roller taking up web-as the other roller gives it out, and vice versa. Both looping rollers e and j are controlled by the cam i From the'looping roller jth'e web passes to the delivery rollp which is driven in unison with the feed rolljb.

As shown in Fig. 3' a bevel pinion 4 is affixed to one end of the roll d'and meshes with a bevel pinion e ch a vertically disposed shaft 5 journaled in brackets: 5 attached to one of the side frames of the pr'ess,

and having a bevel pinion 6 on its upper end meshingwith a bevel pinion 6 on the shaft of the roll 39.

The feed roll dand made of such diameterth-at they will" for each rotation feed and deliver the exact length of web required for each newspaper delivery roll p are at each rotation thereof. The feed roll is preferably provided with the usual coacting tapes'al to assist in feeding web; and the delivery roll palso provided with coacting tapes p as indicated in the drawings, such tapes being well known need no further description herein.

From roll p the web is led to and over spacing. roller 9 mounted in arms 1' on a rock shaftr, journaled on the frame and provided with suitable means (not shown) for adjusting and holding the roller g in the desired position. The roller Q is used "to adjust the length of web between the deliv ery roll and the cutting cylinders so that the cutting cylinders will sever the papers in the margins between the successive papers, after the web has passed the folder former.

The. webqis slit longitudinally as it passes over the'roll p by means of a slitter p of any suitable construction. as indicated in the drawings. The halves of the web after they pass the; roller are turned over angle bars S,S.- and directed thereby toward the folder located at one side of the press. As shown in Fig, 3 one half of the slit web passes rectly to the out feed roller 9 at the top of the former t while; the other half of the web passes over a roller 25 down under an adjustable roller 6 then up to the roller 9 where the split webs are assembled before passing down the former t of the folder.

The former t is of the usual construction and thereby the two assembled sections of the web are folded into page width, and the thus folded four thicknesses of web pass down between-the pinching rollers a and u and. between the male and female cutting cylinders 42 and t whereby the webs are severed into page lengths. Just before the portion of the web depending below the cylinders o and o is severed, it is tucked between the folding rolls n2 and x by the action of a tucker blade 10 and thus the paper'is given the half page fold. The tucker bladew may beoperated in the usual manner. The severed paper is then carried by usual tapes m and 00* up over the last pair of folding rollers y, y over which the said half page folded papers are arrested by a stop, and when properly positioned the pa' pers are'tucked down between the rollers 3 y by tucker blade 2 and packed in the usual packer box 2 The folding mechanism per se form no parts of the present invention but a novel feature of the invention is the means for operating the folding mechanism synchronously with and directly from the press without using gearing or pulleys. For this purpose the folder is so located that the end of the cylinder v is in direct alinement with the axis of the shaft C carrying. the main cranle gears C. To the inner end of the shaft of the cutting cylinder V is attached a crank 42 the'outer end of-wliich isco'n nected to'a smaIlwrist pin D attached to the outer end of the wrist pin D by which the pitman E is connected to the crankgear C. By this means for each revolution of the crank gear 0 the cutting cylinder 01 will make one revolution, beingac'tuated by the crank 42 directly" from the crank wheel C. By this-means the transmitting-shafts and gearings usually required for drivinga 7 folder insynchronism with the press are dis pensed with.

, The cam 38 foroperating the trying the tucker blade 2 maybe mounted on a shaft 38 connected with the feed roll 03 (see Fig. 3). he cam 37 foroperating the usual packing lever maybe operated by a cam 37 on the shaft 38. these parts like shaft (Z being also operated in time (1 to 1) with the other parts-of the folder and press.

cation of the cross heads. At the outer end of the bed i), and at.

the end of the press adjacent the web roll, is an ink fountain ll having a roll U An arm 12 is pivoted on the fountain and carries a pawl 12 adapted to turn'the form- 1 tain roll" step by step when the arm 12 is vibrated. Arm 1.2 is adapted to be raised at each out-ward stroke of cross heads G by. a cam 13 on the cross head G, so as to shift the fountain'roller'each tnn'e'that the cross.

heads are moved to the limit of their out ward stroke toward the web roll. f'From; the fountain roller the ink 15 taken by a ductor roller V mounted on the cross heads G and from ductor roller V the ink is transferred through intermediate distributing rollers to the form rollers Z.. A similar fountain U ismounted on the feed endof. the press and at the outer end ofsbed 0 the fountain roller being operated by a lever 12' operated by'a cam 13 on cross; heads G as the'latterreach the end of their outward stroke. ink is taken from foi'intain {l by a ductor'roller V on cross heads G and transferred through interme:

construction of the inking thereof is necessary.

diate distributing rollers Y to the form rollers A No claim is made herein .for the speclfic therefore no t more detailed explanation The operation of'the various P21ItS',Wlll' be clear from the foregoing but may be'suminarized as follows.

The supply of web from the roll "W is automatically, controlled [by the governor arm 39' carmechanisms roller 0 in the usual manner so that an ample amount of free web is maintained in the press to supply the demands of the feed roll (Z but any tendency of'the web roll to feed in an excess supply of web" will be arrested by the-brake 20, which is-auto matically controlled-by theposition of the lever 0.

From the roll W the web to is led over the idler launder looper (1 past idlcrs b b to'the feed. roll (Z by which it is fed uniformly and continuously then passing over idler 6 over the loopin rollerc over idlers b 6 to roller bon tie crossheads G then under cylinder I up over guide 6 to the register roll 6 Then it returns over the guide I) to the guide Z) on cross heads G then under cylinder I up over guide 2) to the second looping rollergj then to the delivery roller then over guide q andthen to the angle bars S, S

and to the folder as above described.

The delivery roll. operates continuously but in unison with the feed roll and the looping rollers ea-y'.are so arranged and operated that on the printing stroke of the press the movement of the web between the guide roller 6 and guide roller 6 is arrested, although theeweb is continuously fed in and delivered. One side of the web is impressed by the cylinder I upon the forms N on the bed 0. The opposite side of the web is impressed by the cylinder 1 upon the'forms N on bed 0 At the end of theprinting'stroke (say the stroke of the cylinders toward the web 1 roll V1 the cylinders are thrown off impressionv by action of the cam Q? engaging lever P and the cylinders then return off impression over thefbeds toward the driv ing end of'the press to the-position shown iii-Fig. 1. As the cylinders reach the end of their off impression stroke they are thrown on impression by the levers P engaging the cams Q. On each or printing stroke of the cylinders and just before and during the printing operation the looping rollers ej are moved so as to stop the movement of the portion ofweb between the idler guide rollers b and I); but upon the completion of the printing operation and after the cylinders are thrown off, the looping rollers ej are operated so as to shift through the press between the rollers b and 6 as much web as had been fed into the press during the printing operation.

This amount of web is shifted through the :press betweenthe beds and cylindersuwhile the impression is off in addition to the 1 amount of web which is fed into and delivered from the press. by the continuously operating feed and delivery rollers during the time that the impression is thrown oil.

With this press-for each complete reciprocation of the cross heads a perfected newspaper is printed, folded to quarter page size, and delivered into the packer box by the mechanisms hereinbefore described.

VVhat I claim is:

1. In combination with a printing press having reciprocating cross heads, impression cylinders journaled in said cross heads, a shaft having cranks and connections between said cranks and cross heads, a folder beside the press having cylinders parallel with the impression cylinders, and one of the cylinders being in axial alinement with the crank shaft; and a crank on one of the folder cylinder shafts connected with an adjacent crank on said shaft, whereby the folder cylinders are operated synchronously with the cross heads.
